moreMany difficulties can occur during the well is being drilled directionally, as cuttings may accumulate either in a bed at hole high angles. It is to highlight that the speed of the cuttings depends on the geometry of the drilling and the amplitude of the ROP. Hole cleaning is still among the most important problems to solve during the drilling operations. The difficulty in removing cuttings bed during drilling appears due to the interaction between drilling mud and the cuttings in cuttings bed leading to the formation of a cuttings bed gel. Inefficient cleaning of the wellbore can cause decrement in the stuck pipe, lost circulation, wellbore instability, high torque and drag, loose control on density, bad quality cement jobs, etc. These problems have a major impact on the economics of the drilling process. Optimization of the hole cleaning during the drilling operations is very important to enhance the drilling rate. In this study, the Rubiandini and Zhou models have been applied to...
